Assuming Date is yyyymmdd and Time is hhmmss: here is my attempt at pseudo code:
1) create a work table or Common Table Expression to
get max of (Date * 1000000) + Time by Company, Item, Code
2) select *
from "a file" join "work table"/"Common Table Expression"
on "a file".Company = "work table"/"Common Table Expression".Company
and "a file".Item = "work table"/"Common Table Expression".Item
and "a file".Code = "work table"/"Common Table Expression".Code

Subject: SQL Question
I have a file with the following fields:
Company 2 0
Old Value 10A
New Value 10A
Date 8 0
Time 6 0
There can be many records for each code for each item within a date.
I need to get the most recent record for a given company/item/code.
How would I do this in SQL?
